REINHOLD B. MARSHKE,OF OHAFFEE, NORTH DAKOTA.

SPECIFICATION forming part of Letters Patent No. 684,610, dated October15, 1901.

Application filed April 8, 1901. Serial No. 54,784. (No model.)

T0 at whom it may concern:

Be it known that I, REINHOLD B. MARSHKE, a citizen of the United States,residing at Ohaffee, county of'Oass, and State of North Dakota, haveinvented new and useful Improvements in a Combined Screen and StormDoor, of which the following is a specification.

My invention relates to improvements in combined screen and storm doors;and it pertains more especially to the construction and arrangement ofthe removable panels, which are detachably secured in the frame of thedoor in front of the wire screens and to the elastic fastening-piecesinterposed between the edges of the removable panels and the edges ofthe surrounding frame.

The construction of my invention is explained by reference to theaccompanying drawings, in which-- Figure 1 represents the front view ofa door comprising my improvements. Fig. 2 is a horizontal section drawnon line so a: of Fig. 1. Fig. 3 represents a transverse section of oneof the panels removed from the doorframe. Fig. 4: is a detail showingthe position of the elastic fastening-pieces as the panel is beingforced in place into the apertures of the inclosing door-frame, theposition assumed by the retaining-pieces when said panels are in placebeing shown in Figs. 2 and 5. Fig. 5 is a detail view showing theretaining-pieces resting in the locking-apertures.

Like parts are identified by the same reference-letters throughout theseveral views.

The frame A comprises the vertical side pieces B, cross-pieces G, andcentral pieces D, all of which are joined together in the ordinarymanner.

E represents the ordinary pieces of wirescreen cloth, which are securedto the inner surface of the door-frame in the usual manner.

F represents the movable panels, which are provided around theirmarginal edges with elastic retaining-strips G. The inner marginal edgesof the door-frame are grooved out longitudinally on all sides to formconcave recesses H for the reception of the free edges of the elasticfastening-pieces G when said panels F are in place in the frame. The

panels F are also provided around their marginal edges with recesses Ifor the reception of the free edges of said elastic fasteningpieces,which edges are folded back therein temporarily as said panels are beinginserted in the apertures of the frame, as indicated in Fig. 4. It willbe understood that when said panels are in place, as shown in Fig. 2,said pieces G will be thrown out by their own elasticity into theposition shownin such figure, in which latter position their free edgesimpinge against the opposing surfaces of said cancave recesses and holdsaid panels securely in place, while they also serve the secondarypurpose of packing or weather strips to exclude air.

It will be understood that by this device a single door is adapted toserve the twofold purpose of a screen-door in summer to exclude insectsand a storm-door in winter to exclude cold, whereby the expense of twodoors and the necessity of taking down one door and putting up anotherfor such purposes is avoided.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In that class of doors, comprising a doorframe, screens and removablepanels, adapted to be temporarily secured in said frame in front of saidscreens, the combination with the marginal edges of the removablepanels; of elastic retaining-pieces, adapted, when said panels are inplace in the frame, to impinge against the opposing edges of said frameand hold said panels in place, substantially as set forth.

2. In a combined screen and storm door, a doorframe having the innermarginal edges of its screen-apertures provided with longitudinalrecesses serving as bearings for the fastening-pieces of the removablepanels, in combination with permanently attached screens removablepanels; and elastic panelretaining pieces, said elastic pieces beingpermanently secured at one edge to the edges of said panels, andadapted, when said panels are in place, to impinge at their oppo siteedges against the concave walls of said recesses, and hold said panelsin place, all substantially as and for the purpose speci fied.

In testimony whereof I affix my signature in the presence of twowitnesses.
